Raman spectroscopy as a versatile tool for studying the properties of graphene.
The state of the art, future directions and open questions in Raman spectroscopy of graphene are reviewed, and essential physical processes whose importance has only recently been recognized are described.
Metal–insulator transition in a weakly interacting many-electron system with localized single-particle states
Uniaxial Strain in Graphene by Raman Spectroscopy: G peak splitting, Gruneisen Parameters and Sample Orientation
We uncover the constitutive relation of graphene and probe the physics of its optical phonons by studying its Raman spectrum as a function of uniaxial strain. We find that the doubly degenerate E(2g)…
Electron-electron interactions and doping dependence of the two-phonon Raman intensity in graphene
Raman spectroscopy is a fast and nondestructive means to characterize graphene samples. In particular, the Raman spectra are strongly affected by doping. While the resulting change in position and…
Graphene mode-locked ultrafast laser.
The optoelectronic properties of graphene are exploited to realize an ultrafast laser and pave the way to graphene-based photonics.
Raman spectroscopy of graphene edges.
A detailed Raman investigation of graphene flakes with edges oriented at different crystallographic directions is presented and a real space theory for Raman scattering is developed to analyze the general case of disordered edges.
Observation of three-dimensional massless Kane fermions in a zinc-blende crystal
Graphene and topological-insulator surfaces are well known for their two-dimensional conic electronic dispersion relation. Now three-dimensional hyperconic dispersion is shown for electrons in a…
Brightening of dark excitons in monolayers of semiconducting transition metal dichalcogenides
We present low-temperature magneto-photoluminescence experiments which demonstrate the brightening of dark excitons by an in-plane magnetic field B applied to monolayers of different semiconducting…

- 6 March 2007
We present a detailed calculation of intensities of two-phonon and four-phonon Raman peaks in graphene. Writing the low-energy hamiltonian of the interaction of electrons with the crystal vibrations…
Possible experimental manifestations of the many-body localization
Recently, it was predicted that if all one-electron states in a non-interacting disordered system are localized, the interaction between electrons in the absence of coupling to phonons leads to a…
